MAG Ex Incremental und MAGA Ex Absolute
MAG Ex (incremental) and MAGA EX (absolute)
Extremely rugged and explosion-proof
Our bearingless magnetic encoders MAG incremental have been proving their qualities for a long time in applications exposed to extreme environmental conditions. Thanks to their compact construction they are particularly able to demonstrate their strengths when deployed in confined spaces. Ex certification is a new development for the MAG Ex incremental model. Consequently, we are able to increase the spectrum of applications for these extremely rugged, contactless functioning encoder systems. The MAG Ex is certified for harsh environments subject to explosion hazards. Examples of the new fields of applications for the encoders include oil and gas production, offshore platforms, pipeline compressor stations and petrochemical installations.
Tailor-made solutions
With a wide variety of additional options MAG/MAGA Ex facilitate tailor-made encoder integration solutions. For example, these include a second scanning head to enable transmission of redundant signals. And it is possible to fit both magnetic encoders with an external transmitter/decoder to provide additional FOC signal transmissions up to 1000 meters.
MAG Ex incremental and MAGA Ex absolute
The explosion-proof encoder systems MAG Ex incremental with HTL or TTL output signals are available with immediate effect. Ex certification for the encoder systems MAGA absolute with SSI output signals is in preparation. Both the MAG Ex incremental and the MAGA Ex absolute will receive ATEX certification for Zone 2.
Long lasting and flexible
Both versions of our Ex certified magnetic encoder systems are extremely rugged and designed for a long service life. They are nonwearing thanks to their bearingless design and contactless scanning functionality. A special stainless-steel protection cover additionally shields the encoders from the effects of the environment. The scanning head is seawater-proof by design (IP68) and, as a consequence, is also suitable for offshore applications. Furthermore, because they can be directly attached to shafts with or without a free shaft end our MAG Ex incremental and MAGA Ex absolute encoders offer maximum engineering freedom. The split pulse wheel option is a practical alternative for retrofitting and upgrade projects.
